Atomizer and electronic cigarette having the same

Abstract

An atomizer includes a liquid storage pipe having a liquid storage chamber, a connecting member, an adjusting member rotatably received in the connecting member, a pressing cover, and an air intake cover provided with a clamping claw capable of driving the adjusting member to rotate. A bottom wall of the connecting member is provided with a first liquid inlet hole communicating with the liquid storage chamber. The adjusting member is provided with a third liquid inlet hole corresponding to the first liquid inlet hole. The pressing cover is provided with at least one clamping groove. When the air intake cover is rotated, the clamping claw drives the adjusting member to rotate along the clamping groove, to cause the third liquid inlet hole to communicate with the first liquid inlet hole or to cause the adjusting member to close the first liquid inlet hole.
